I'm sure he's scared, just putting on a brave face. He has postponed the dialysis because he "feels fine" even though toxins are building up in his system.
Leo fella says he would install a port himself if he could. Fuck that. He would never go through with it.
Like others, I respect his honest, walking his own path, etc. But I just don't get the 'feelin fine' logic here. I'm no expert, but surely the earlier you start dialysis, the more cumulative damage you prevent - meaning lower impact on the body, lower need for future interventions, meds, increased longevity, improved prognosis, etc.
